That is next on the major tool list. I have all the components and plan on printing parts in PLA and then encasing the plastic parts in ceramic slip and sand layers and then firing the thing to burn out the plastic.
What I have left is a hot ceramic mold that I can then fill with aluminium or iron...
This method is used for making cast parts with internal passages and flanges that can not be machined otherwise.
Yes I could use the traditional sand cores but then I would have to make molds for all the cores as well. With 3D printing I could print all of the "cores" in place in the first go round...
